The BBC's director of global news Peter Horrocks said: "The jamming of shortwave transmissions is being timed to cause maximum disruption to BBC World Service English broadcasts in China.

"The deliberate and co-ordinated efforts by authorities in countries such as China illustrate the significance and importance of the role the BBC undertakes to provide impartial and accurate information to audiences around the world."

The BBC added in a statement: "Though it is not possible at this stage to attribute the source of the jamming definitively, the extensive and co-ordinated efforts are indicative of a well-resourced country such as China.

"The BBC strongly condemns this action which is designed to disrupt audiences' free access to news and information.
